Add playlist visual indicators and split panel layout

- Highlight files/folders in playlist with bold white text in file tree
- Show folders as in-playlist when they contain playlist items
- Split UI into files (70%) and playlist (30%) panels
- Make selection bar bold when over playlist items
- Fix search to keep selection on found item after pressing Enter
